Someone listened. But now I think I can see why they made their original choice.

Sometimes art direction is just art direction. Presumably there's only so much time to do photo shoots like these, and maybe they just picked the image they thought looked the best. In the new shot, I think her hunched shoulders makes her look a bit tense and defensive. Also, in the layout it looks like she's about to blow Hawkeye's face off.

Oh well, can't please everyone. Now we have it both ways, so I'll quit complaining making observations.
